Are you planning to ride off road or solely on tarmac?
If your determined to stick to a 2T and you need off road ability then its impossible to overlook a DT125, they're as common as muck all across europe, tons of spares everywhere. Ive seen them clear 40ft tabletops round our mx track and they can withstand a lot of abuse.
The only trouble now is finding one that hasn't been crashed, bent, stolen, jumped and ran out of oil.
If your going to stick to the tarmac, consider a TDR125, similar motor to a DT but a bit of wind protection and more road manners, very common in Europe.
There are no commuter/comfortable 2Ts left really, the 2Ts only lingered on as race reps and off road bikes through 90-00s.
New there's really nothing out there.
Sorry about the essay, hope it helps
